What PSU

[The restless fool]

I'm planning to use a

I9-900ks

2080ti kingpin

Nzxt kraken x72 360mm AIO

Gigabyte Aorus Z390 Ultra

I'm planning to overclock obviously (not LN2) I was wondering what PSU would be adequate some say 1000 watt others 850 watt.  Could it reduce performance if I use a higher PSU than I need?

A decent 650W unit would suffice.

 

RMx from corsair is a good line

It wont. but a bit of headroom helps with eh OC.

OK thank you for your help 1000 watt it is

I'm sticking with EVGA for the PSU and going with 1000 watts to maximise oc headroom.

That's like buying a pair of jeans that are 10 feet long to only grow to have 3 foot long legs

 

Headroom is good, yes- but 1000 Watts is redundant. You really won't ever need anything more than 650. If you want this "headroom" to feel more comfortable get a 750W unit.

 

And sticking with one brand? Why? If you're looking at EVGA's G3 units, stop.

What EVGA unit? EVGA has quite a few arguably bad units and you need nowhere near 1000W for this system, my i9 9900K at 5ghz with a TITAN V works flawlessly on a 650W unit.

Its more important to have a GOOD powersuply. and 1000Watt doesnt make it good.
You have better luck OCing with a high quality 700Watt then a shitty 1000Watt.
So do your research and look in the PSU tier list that has a lot of PSU's collected and shows their quality.

Cus you dont want much 'ripple' on your line wether the PSU gives 100Watt or a 1000...

Uhm you ask a question, get an answer then you make up your own thing?
Why ask to begin with then?

If there were only 2 options, should have told us.

How will headroom help with OC...?

you'd barely be able to get above 550 watts with good overclocks.

 

any quality 650 watt PSU gets the job done and then some, I recommend the Bitfenix Formula Gold or Whisper M

I was looking at GQ units now I'm looking at all of the brands people have reccomended, I assumed a large company like EVGA would sell decent reliable products. After reading a few reviews I realise I was wrong.

As you overclock the components require more power.

1000W can do 2X2080ti's with a bunch of other stuff.

 

https://www.bequiet.com/en/psucalculator

I recommend this calculator as it is not as over-rated as some of the other ones.  I find it useful.

 

but hey, if you are dead set on 1000W, up to you.  

 

Browse this:

 

Personally, I stick with Corsair for the warranty period.  my latest purchase is 850W HXi

 

I also have an EVGA 850W P2  - way overkill for my system.  bigger psus' really only i would recommend for 2X gpu setups.

 

bequiet generally have more multi-rail designs, which i like.

corsairs hxi units have a "multi-rail" switch.  

==

Also; check efficiency curves and noise profiles of the PSU's; use the calculator for Your setup, which you can plop in any proposed OC and various peripherals etc you might be contemplating for future upgrades (If Any super high end thing is in your mind)  I don't ever plan on doing multi gpu or multi system setups these days.  better to upgrade a single gpu in my opinion later on down the track.

Realistically, as others have noted, you are more like to be in this range (550-750W)  and quality psu's are more important than Watt Ratings.

I'm now looking at all of the manufacturers on this thread I didn't ask for a manufacturer recommendation I asked which wattage would be best.

There's a lot of information thrown left and right, I can see how you got confused or misled

Thank you for your advice I'm going with corsair the main reason I posted this was the kingpin uses 3 x 8 pin pcies and wanted to see if anyone had experience with them. I'm not sure if anyone does own one but they are thirsty, also the i9 9900ks draws 127 watts compared to the previous model (i9-900k) of 95. Everyone gave me direction on brand and probably decided what was best before looking into the hardware, for example they kingpin can draw upto 400 watts without LN2 cooling. So I'm not sure a 650 watt would be sufficient I've had to research these numbers, should of just done this in the first place. But I did find a new psu supplier.

I would look at the bequiet calculator as a guide on wattage.

personally i don't have a problem with overkill. 

not much price difference between a 750 or 850 w psu...so i usually end up with the 850.  with a power hungry gpu in mind.  my current rig would no doubt run fine with a 550w.  but i have run some power hungry systems in the past that i measured at 500+W (but this is from the wall) so....what the desired buffer to max output power is (which is what the rating of the psu means, and NOT power drawn from the wall outlet) ? I err on the side of caution.

 

so, base it on the bequiet calculator.  add your desired buffer. and presto, you have your psu sorted.

I'd say an 850W will easily cover "any" (bar some totally over the top exception to the rule thing) single gpu system.  people will say it is too much.  i don't care.

you have to base your decision on what you are comfortable with.

 

i've heard all sorts of 'rules' .  One that comes to mind is the 60% rule. (peak load percentage of max. output power)  Personally i don't want to go above 75% of the psu's max. output power rating.

 

And I don't want the psu's fan to ramp up in speed either.
